Working principle: before glass metal blanking, the glass metal of melting being transferred in mixing device 60, driving motor driving stirring Axis 62, which rotates, simultaneously drives the mixing drum 63 being fixed on agitating shaft 62 to rotate, when mixing drum 63, since outer deflector 64 is led with interior The hand of spiral of flowing plate 65 is on the contrary, the spiral helicine outer deflector 64 on mixing drum 63 can be in mixing drum 63 with inner deflector 65 It is inside and outside to generate two different effects, so that the glass metal of the two sides of mixing drum 63 is formed flowing different on vertical direction, and It realizes that the glass metal of two sides complements each other, from keeping the glass liquid stirring of different component uniform, is formed convenient for subsequent glass cutting stock.

When glass metal blanking, glass metal is placed into feed hopper 304, is pulled and is dialled by handle 320 and the first slide bar 313 Flitch 312 moves switch-plate 312 along the first slide bar 313 and 304 edge of feed hopper, and glass metal is dialled in feed hopper 304 It is even, it opens the first driving motor 307 and drive pulley 317 and first gear 318 is driven to rotate, pass through first gear 318 and the The engagement connection of one rack gear 308, moves forward device along first sliding groove 311, drive pulley 317 drives driving pulley 309 and driven pulley 310 rotate, blanking wheel 305 drives by driven pulley 310, the glass metal in feed hopper 304 produced It is laid in 111 surface of molten tin bath, wheel 306 is flattened and is transmitted the drive rotation of belt pulley 309, under the position due to flattening wheel 306 is lower than The position of material wheel 305, the glass hydraulic flat by the tiling of 111 surface of molten tin bath are in certain thickness, flatten molding and complete.

Drawn upper transition roller table after glass hardening, cooling, the sulfur dioxide gas in fluid reservoir 501 passes through connecting tube 502 It is conveyed, flowmeter 504 is provided in connecting tube 502, can be united to flow of the sulfur dioxide gas in connecting tube 502 Meter, when flowmeter 504 detects that the flow of sulfur dioxide gas becomes smaller, PLC controller 513 controls the second servo motor 510 Rotation drives fixed plate 509 to rotate, so that screw shell 508 be driven to rotate, 514 inner wall of third sliding slot is fixed with the second screw thread Bar 507, the second threaded rod 507 are threadedly coupled with screw shell 508, and limited block 511 and slideway 512 match, can be sliding to third Block 506 is limited, and is prevented third sliding block 506 from rotating, be slided up and down third sliding block 506 can only, to make the second threaded rod 507 can only slide up and down, and when screw shell 508 rotates, so that the second threaded rod 507 be driven to slide up and down, make third sliding block 506 slide up and down, and when third sliding block 506 slides into lowermost end, connecting tube 502 is closed, and sulfur dioxide gas will not be from control shell Pass through in 505, when third 506 slowly upward sliding of sliding block, increases the flow of sulfur dioxide gas slowly, thus to dioxy The flow for changing sulphur gas is controlled.

When the tin liquor in molten tin bath 11, which is oxidized production stannic oxide, is attached to tin liquor surface, glass thus will affect Quality, so just needing to clean up these impurity.After glass is drawn upper transition roller table, then pass through the first control panel 411 It controls first servo motor 401 and drives the rotation of the first threaded rod 402, to drive the second support plate 404 to far from the first servo One end of motor 401 is mobile, when being moved to the end of molten tin bath 11, controls the second driving motor by the first control panel 411 406 drive second gear 408 to rotate, and second gear 408 drives the second rack gear 407 to move down, so that fishing net 410 be driven to move It moves in tin liquor, first servo motor 401 is then controlled by the first control panel 411 and is inverted, to drive fishing net 410 Toward close to the movement of one end of first servo motor 401, the impurity on tin liquor surface can thus be rushed to close to the first servo electricity One end of machine 401 passes through the second driving of the first control panel 411 control when fishing net 410 is moved to the end of molten tin bath 11 Motor 406 inverts, and moves up fishing net 410, so that the impurity in tin liquor has been salvaged, for glass processing molding next time It prepares.

After finished cutting device is transmitted to from transition roller table, glass is placed into third groove 710, third driving motor 707 drive rotating block 708 to rotate, and rotating block 708 drives drive roll 704 to rotate, and drive roll 704 makes driven voller by belt 703 and live-roller 722 rotate simultaneously so that glass moves under the action of 703 drive roll 704, driven voller live-roller 722, When in glass motion to limiting slot 714, slide plate 713 is pressed downwards, the distance between drive roll 704 and driven voller 703 are in cunning Plate 713 changes when moving, and belt drives guide wheel 721 to move, so that the holding between 704 driven vollers 703 of drive roll Transmission, does not influence follow-up work, drive roll 704 is detached from one of rotating block 708, and the end of third threaded rod 716 enters In another rotating block 708, since the end of third threaded rod 716 and drive roll 704 is square setting, so that drive roll 704 and third threaded rod 716 rotate with rotating block 708, Four-slider 717 is engaged with third threaded rod 716 by internal screw thread Connection cuts glass, after cutting, slide plate 713 is in limit spring 709 so that glass cutter 718 is moved in glass surface Elastic force effect under state when being restored to static.
